The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We propose exact but compact expressions that describe the impact of each of those non-idealities on the output spectrum. We derive the distribution of the power of the induced spurs and replicas, critical for yield-oriented derivation of sub-ADC specifications.

C2weakest assumption

The derivations treat offset, gain, and timing skew as the only non-idealities while assuming all sub-ADCs are otherwise ideal and that the mismatches are statistically independent across channels; this modeling choice is implicit in the abstract's focus and would invalidate the closed-form expressions if additional impairments or correlations dominate.

C3one line summary

Derives exact expressions for spectral spurs from mismatches in interleaved ADCs plus power distributions for yield-oriented sub-ADC specs.
